Plane Curve Singularities,rsection multiplicity of two (irreducible) plane curve singularities (., o) and (., o). This number can be calculated as follows. Consider the normalization ℂ{.} of .., and let (., o) be given by . = 0. Via the inclusion .. ∈ℂ{.}, we can consider at . as an element of ℂ{.}. Then the intersection mul命令变成大炮 发表于 2025-3-25 11:57:55
Classification of Simple Hypersurface Singularities,acy Theorems. Let m be the maximal ideal of ℂ{..,... ,..}. A function / is called (right) .-determined if for all elements . with . ∈ m.. the functions / and . are right equivalent. In particular, a .-determined . is right equivalent to a polynomial of degree at most .. A function is called finitely把手 发表于 2025-3-25 16:57:31
Textbook 2000ll do in this book, as the "commutative algebra" one needs in local analytic geometry is somewhat more difficult: one has to cope with convergence questions. The most prominent and important example is the substitution of division with remainder. Its substitution in local analytic geometry is called铺子 发表于 2025-3-25 23:08:41

0932-7134 (over an algebraically closed field). As one often reads in prefaces of int- ductory books on algebraic geometry, it is not so easy to develop the basics of algebraic geometry without a proper knowledge of commutative algebra. On the other hand, the commutative algebra one needs is quite difficult t过分 发表于 2025-3-26 07:11:41
Approximation Theorems, system of analytic equations has a formal solution (which is sometimes really not convergent) then we can find a convergent solution to this system. Even more, we can approximate the formal one by convergent ones up to a given order.肉身 发表于 2025-3-26 09:30:02
